Definitions

  • the invention relates to a method for updating the local management system in at least one network element of a telecommunications network, the local management system consisting of at least one network element agent stored in a network element management unit of the network element and a network element manager.
  • a plurality of data connections via several network elements interconnected are constructed, maintained and degraded again.
  • the network elements have the task of switching or setting up and administering data connections.
  • the control of the respective network elements can be carried out via individual local management systems integrated in the network elements.
  • Such a local management system is usually composed of two cooperating management system modules, the network element agents and the network element managers.
  • the network element agent is integrated in the network element to be managed in a network element management unit and manages individual management objects.
  • management objects may include information, for example, about the structure or architecture of the network element or about the switching state of the respective network element or the telecommunications network.
  • these management objects are monitored and controlled via the network element agents - see for example the patent specification US 5,651,006 , Columns 1 to 3.
  • the network element manager in particular manages and controls the network element resources assigned to a network element agent.
  • the network element manager is connected to the network element agent via a data connection, the management data being exchanged via different network management protocols.
  • Such management interface specifications are subject to constant change, updating in the already existing local management system modules, i. both in the network element agents and in the network element managers. After updating these local management system modules in the respective network elements, incompatibilities between the network element agent and the network element manager may occur during the commissioning of the local management system. Possible conflict situations may be due to the fact that on the one hand the network element agent does not recognize isolated control commands of the network element manager and consequently does not execute or the real operating states of the network element are not correctly detected and reproduced by the updated network element agent.
  • Examplementing OSI Agent / Managers for TMN Discloses a method for the automatic generation of network agents (partly with a management function).
  • the object of the present invention is to provide a novel method for updating a local management system in a network element by which incompatibilities between the updated network element agent and the updated network element manager can be avoided.
  • the essential advantage of the inventive method is that an updated network element agent and an updated network element manager are generated by a common generation mechanism directly from a predetermined management interface specification and at least the updated network element agent in the network element management unit of the network element to be updated is loaded.
  • the inventive automated and joint generation of the network element agent and the network element manager directly from the present management interface specification a compatibility of the two local management system modules is guaranteed, whereby the error rate of the local, to be updated management system is greatly reduced. This additionally significantly reduces the time required for commissioning the local management system after the update.
  • the updated network element manager stored in a central unit of the telecommunications network or also loaded into the network element management unit of the network element to be updated.
  • the updated network element agent and the updated network element manager are advantageously loaded via a data connection using a data transmission protocol from a user computer into the network element management unit of the network element to be updated.
  • the loading of the updated local management system modules into the network element to be updated can be automated and spatially independent.
  • HTML management interface specification is generated by the common generation mechanism in Hyper Text Markup Language (HTML) format, which is stored along with the updated network element manager.
  • HTML Hyper Text Markup Language
  • Such an HTML management interface specification in HTML format is easily and up-to-date via a web browser. As a result, only the functionalities of the local management system are displayed, which are currently available for the network element under consideration.
  • the block diagram shows a central unit CU, for example a central server unit, a telecommunication network TKN and one of a plurality of network elements NE present in the telecommunication network TKN.
  • the network element NE comprises a network element management unit MSU in which, for example, a network element agent NE-A and a network element manager NE-M are stored.
  • the storage of the two local management system modules NE-A, NE-M can optionally also take place in separate units in the network element NE.
  • the network element NE can be connected to the central unit CU of the telecommunications network TKN via a data connection.
  • the central unit CU has at least one memory unit SU, in which the current management interface specification IS is preferably stored in the ASCII code. In this case, different versions or only parts of the management interface specification IS can be stored. Further, in the central unit CU, there is provided a generation mechanism module GMM in which the common generation mechanism GM for generating the updated network element agent NE-A as well as the updated network element manager NE-M is realized directly from the stored management interface specification IS. The common generation mechanism GM is at least partially realized by a parser.
  • a central network management system unit is provided by way of example in the central unit CU, with the aid of which the entire network management within the telecommunications network TKN is carried out centrally.
  • the updated management interface specification IS which is present in ASCII data format, for example a Tl-1 interface specification, is loaded into the storage unit SU of the central unit CU.
  • the network element agent NE-A and the network element manager NE-M are generated as machine-readable code from the management interface specification IS present in the ASCII code. This generation may alternatively be performed in a separate unit - not shown in the figure - separately from the central unit CU of the telecommunication network TKN.
  • the updated network element agent NE-A and the updated network element manager NE-M are then loaded directly into the network element management unit MSU of the network element NE to be updated via a data connection or via a data interface of the central network management system NMS, wherein the network element manager NE -M alternatively in a central memory unit SU of the telecommunication network TKN or in a storage unit of a portable user computer PC "downloadable" can be stored.

  • a data transfer protocol for example the File Transfer Protocol (FTP)
  • FTP File Transfer Protocol
  • the updated network element manager NE-M realized, for example, as a JAVA applet.
  • the "download" of the network element manager NE-M via the Internet data transmission protocol IP can be performed.
  • Such a "download” is possible via any standard user computer PC having a web browser, so that the management of the updated network element NE by means of the network element manager NE-M loaded on the user computer PC is spatially separate from that to be managed Network element NE is feasible.
  • the JAVA applet is executed on the web browser of the user's PC.
  • a data connection to the updated network element agent NE-A is then established and via the implemented network management protocol, for example the TL-1 interface protocol, control commands cc are generated by the network element manager NE-M are transmitted directly to the network element agent NE-A executed in the network element management unit MSU.
  • the network element agent NE-A executes the received control commands cc, for example TL-1 control commands cc, whereby actions assigned to the control commands cc are triggered in the network element NE.
  • an HTML management interface specification HTML-IS in hyper-text markup language format is generated directly from the management interface specification IS present in the ASCII code via the common generation mechanism GM.
  • This HTML management interface specification HTML-IS is stored together with the updated network element manager NE-M either directly in the network element NE to be updated or in a central memory unit of the telecommunications network TKN "downloadable".
  • HTML-IS which can be displayed with the aid of a conventional web browser, a user can directly via his user computer PC, the control commands available for the respective network element NE cc or control options query and thus receives information about the individual parameter options of the respective available control command cc.
